The San Francisco Giants get an opportunity to play spoiler against the team they'd most enjoy spoiling -- the Los Angeles Dodgers -- when the longtime rivals close out the regular season with a three-game series that begins Friday night. Giants ace Madison Bumgarner (6-6, 3.20 ERA), the star of his last AT&T Park appearance with his bat, is scheduled to duel Dodgers left-hander Hyun-Jin Ryu (6-3, 2.00), who pitched brilliantly the last time he faced San Francisco. The Dodgers (88-71) enter the series with a chance to win the National League West, capture an NL wild card or miss the playoff entirely, all to be determined within three games against a team that has beaten them nine of 16 this season.
